Au-modified α-Fe2O3 columnar superstructures assembled with nanoplates and their highly improved acetone sensing properties

Abstract A highly improved acetone sensing hybrid material of Au nanoparticles (Au NPs)-modified α-Fe2O3 columnar superstructures (Au/α-Fe2O3 CSs) was successfully fabricated by two-stage solution processes. Firstly, a simple glycerin-assisted hydrothermal method was used to assemble single crystalline hematite α-Fe2O3 nanoplates into three dimensional (3D) CSs. Afterward, the as-prepared α-Fe2O3 CSs were further employed as supports for loading Au NPs via precipitating HAuCl4 aqueous solution with ammonia. The obtained samples were analyzed by means of SEM, TEM, XRD and EDX. Both pristine and Au-functionalized α-Fe2O3 CSs were practically applied as gas sensors. The results indicated that the hybrid sensor exhibited enhanced responses and selectivity to acetone than the pristine one at the optimal working temperature of as low as 150 °C. Meanwhile, the detection limit could extend down to ppb-level. Such excellent sensing performances are better than those previously reported sensors based on iron oxide nanocomposites, indicating its original sensor application in detecting acetone. The strong spillover effect of the Au NPs and the electronic interaction between Au NPs and α-Fe2O3 CSs support are believed to contribute to the improved sensor performances.
